Application-filed December 1-2. 1918. Serial No. 266,414.

To all LO/b07771 it may concern Be it known that I, Mourns SI-IEKAS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Time-Stamps, of which the following is a specification.

This invention relates to impression stamps and particularlytime stamps characteristic features of which are the horological or time train, the impression train, the driving connection between the two trains, permutation impression elements, a permanent impression pad, and a changeable date line. 7 v

Ordinarily considerable diiiiculty is experienced in so constituting the drive connection between'the two gear trains as to avoid impairment of the mechanism by reason or the vertical blows incident to the use of such a stamp. This difficulty is met herein by the provision of a coupling in the crive which leaves the parts free for vertical rela tive movement without affecting the rotary engagement.

Another source of trouble in such stamps is the inconvenience of cleaning the gear elements of the impression train from the ink and other ginnining agents which creep up about the permutation ti the impression elements into the gears. This is overcome according to the present invention by providing for the easy quick removal of such gear elements by means of a simplified hum of mounting.

A further limitation, of the usual hand stamp is due to the fact that the relation of all the component parts of the impression elements, time, permanent and date line, is fixed as to location; whereas some users I would have a choice, for instance, as to the date being above or below certain other given data imprinted to the stamp. I provide for such preference by making the date line, for instance, adjustable as to position on the die plate, cutting, out the pad to provide a space for range of placement and, after locating the date line, inserting a filler pad to complement the inserteddate line in filling out the space.

' By the provision above stated for adjustable relation of the date line to the permanent expression elements, the stamp-- maker is enabled to accommodate the wishes of his customers in that regard and yet not be required to, keep in stock a plurality of styles of. die plates'and impression pads,

' the adjustability of the type-retaining channel in the plate and the 'radiz'il'op'en space in the pad with the filler portion enabling him to meet all requirements in the make up of stamps. 7

The'features of the invention as herein above generally outlined and theircoopera tion to produce a stamp ot. signal supe 'iority by those skilledin the art as revealed in the accompanying drawing and in the following detailed description based, thereon. It is obvious that the features ol 'constructionare susceptible to modification within a considerable range without the sacrifice of material advantagegand without departure from the essence of the invention, wherefore the drawing and description are to be taken in in an unnecessa- I Fig. 4 is a bottom plan view, omitting the impressionpad except as to the permutation time impression elements and the date line.

Fig. 5 is a section on the line 55 of Fig. 4. and

Fig. 6 is a detailed perspective of the gear:

retaining plate.

Having reference to the drawing in detail, the stamp case is indicated generallyat 11 provided with the operating handle 12 and a base plate 13. The constructionaldetails of the chronological or time motor havenoth- .65 will bereadily understood and appreciated ing to do with the invention and they are not herein illustrated.- The Winding arbor is indicated at 1 1 and the setting arbor at 15, the latter carrying a pinion 16 forming one oi: the elements of the time train. Su1tably journaledin the bracket 17 is theverl tical drive shaftlS carrying the pinion 19 geared w th the pinion 16 at 1ts upper end, and, at its lowerend the crank OI" WI'1Sl 3 pin 2O concentrically disposed with reference to said shaft axis. The second vertically disposed drive shaft 21 has a footstep bearing in the face plate 13 and is journaled also in the bracket 22. This drive shaft 21 carries at its upper end a trough-like upwardly concave channel member 23, transversely fixed to said shaft, the walls of which channel member are suitably spaced apart to provide tl'ierebetween slots within which the lower end of the wrist pin 20 engages loosely. It will be observed that the two head transmission shafts 18and 21 are approximately alined vertically. The connection between the on of the wrist pin :20 and thechannel member 23 is such as to render unnecessary an absolutejalinement of the two shafts. The revoa hit-ion ot the wrist pin about the axis of the uppersha'l'it causes corresponding revolution oi the channel member and a rotation of the lower shaft, the end of the wrist pin traveling from end to end of the channel member. This operation will be clear from an inspection of Fig s1 and 2 of the drawing. lvloreovcr, the loose engagement of the vrist pin 20 within the channel member 23 provides for a vertical movement of the two shafts, the wrist pin 2C being enabled to move up and down within the trough llponthe lower base oi the face plate 1?) is mounted the impression pad ing tie usual permanent impression elements such as the name and address of the user and such appropriate legends as heceived or Paid. Centrally of this pad are mounted the permutation time impression elements indicated generally at 25, and

' including the hour indicating minute nuextending through said face plate and inerals 26 and the revoluble indicating hand 27 and hour hand 27. The hands 27 and 27 are driven by the impression gear train suitably. mounted upon the upper face of the base plate 13 within the stamp case.

herein illustrated this train consists of the relatively movable pinions 28 and 29 on the shaft 30 and the relatively fixed pinions 31 and 82 upon the shaft 5-13. Shaft 30 extends through the plate 13 and carries he minute hand 27, whereas pinion 29 has a boss 29 carriesthe hour hand 27 within the space in dicated by the reference numeral Shaft 21 carrying the channel member at one end has mounted upon its opposite end the pinion 35 which in mesh with the pinion 31 of the impression gear train. whereby the transmission drive connection constituted of the shafts l8 and 21 and their coupling 20-23 serves to drive the impression geartrain from the horological tr The diliic-ulty encountered in devices o5? this sort has been due to he creeping of ink upwardly about the sh...;.3() and the boss of the pinion 2!) by gnnuning the impres sion geartrain. It the various elements oil? this gear train be secured in the usual man- 'ner much inconvenience is experienced in aged endsof the two shafts by means 2-1 for car:

- as to position.

corresponding to the axis of the pinion with a recess or an equivalent stud which serves to position the pinions 31 and 2-32 properly in mesh *ith the pinions 28 and 29 and with the pinion of the drive shaft 21. As the pinion 3i o-mrlies the pinion. 29 the latter isheld in its proper position therein being prevented from jui'nping out of place. To hold the pinion 31 in place, I provide a retaining plate indicated generally at 36, and shown in detail in Fig. (3, this rctainlug plate being apertured at and serve as a journal bearing for the shaft 21, An arm 38 of the plate overlies the pinion 31 while another arm 59 of the reta'ining plate is apertnrml at 4-0 "for the reception of a screw by means of which the ate is held in fixed relation to and the pinion 31, said screw talr into thebaseplate13. In some cases the toot-step bearing in the shaft 21. in the base plate 12-} may be omitted, in wh ch ever-t the retaining plate is provided with an addit onal arm l1 having a do vnturncd mid l2 adapted to engage in the rein the h: e plate whereby angular shift ing of the retaining plate 36 is prevented. ()bviously. all oi the sin 5 -38, 39 and 4-1 may be consolidated by the employment of a date considerable area instead of cutting the same out to prof e lightness the essential feature being that there shall be a portion overlying the impression gear train e mentand al o a the base plate eccen lt will be observed construction outlined of the llllQlQElOn gear removed for cleaning by merely removing the one sci-en "i -E from engagement with the ljxase plate at the aperture 4.0 and swinging the said retaining plate so as to bring the arm "from its overlying"relation to the pinion 31, the shaft 21 serving as an axis upon which the retaining 1; ate is shifted. It is equally clear the; if it is desired to re- 11 ovc the .retai" g plate and the shaft 2i th the channel member it can be done in a lateral direction after ri-zmoving the screw e O tentimes the data carried by the pad it' l is required to be substituted by other matter, using the same stamp. In rearranging of the matter upon the stan'ip it may be desired to change certain portions, as for instance, the date line. to bring the same above or below other matter as, for instance, the legend Paid or Received. in order "to effect this, I provide herein an arrangement whereby the dateline may be changed The base plate 13 is provided with parallel approximately radial slots a l, and a form of known channel memher for holding the date type, indicated ll to si-irround construction and herein at 45, the same having lips at each 1 end for entering the slot and advantageously flanged over as indicated at 4.6 in Fig. 5, whereby be moved backward and forward in the slot to a greater or less distance from the center of the pad. In order to permit of such adjustable relation,the pad is cut away to provide a considerable open space corresponding to that embraced between the slots is as clearly shown in Fi l, and a removable filler pad member at? is provided, which, together with the type-retaining member 45, serves to fill out said space. If the date line isdesired at a point of the stamp farthest removed from the center the. arrangement would be that indicated in F ig. at, whereas if the user desires to bring the date line nearer the center of the pad the relative positions of the filler pad 47 and the type-retaining mem ber 45 would be reversed. I The legends Paid or Received. may be advantageously mounted upon this filler pad member 47 thus providing for the placing of the date above or below such legends.

It will thus be appreciated that I have provided in a hand stamp a device simple in inexpensive in character; a drive connection between the horological motor and the impression gear train which does away with the requirement for exactitude in the alining of the two shafts and also guards against impairment of the mechanism by means of vertically transmitted blows; also a simplified mounting of the gear elements of the impression train whereby the same may be readily removed for cleaning and easily reassembled; also a mounting of the date line on the pad which enables it to be readily adjusted in its relation to the other elements of the impression.
